Had you considered QGIS? QGIS has the ability to import/export GPX so you could conceivably import into QGIS, do your editing, and export the newly tailored traces.<br><br clear="all">SEJ<br>----<br>"Wretches, utter wretches, keep your hands from beans." -Empedocles<br>

I posted this question a few weeks ago and got some answers. I've been<br>
using Prune until now, but it's really not satisfactory. I've also<br>
tried out a couple of the other tools suggested, and they're pretty<br>
bad too.<br>
<br>
Here's my basic use case:<br>
I've just come back from a 4 day bike trip where I collected about<br>
11Mb worth of gpx files, numbered 32.gpx-45.gpx and current.gpx,<br>
spanning about 250km (tracing 1 point per second while it was on). I<br>
want to merge them into one trace, then upload pieces of these to OSM,<br>
and also to some other sites. I want to totally disregard the original<br>
boundaries between traces (which I think represent either the GPS<br>
being turned off/on, or a trace getting too long).<br>
<br>
In short, I need to be able to:<br>
- merge multiple traces<br>
- be able to visually select pieces of a trace to either delete (for<br>
privacy/tidiness) or export<br>
- simplify a trace down to a much smaller number using some smart algorithm<br>
<br>
Preferably with an OSM slippy map type background.<br>
<br>
This sounds like a very small ask to me. I don't need it to directly<br>
interface with the GPS, convert formats or anything. Features like<br>
converting speeds to colour are nice, as are showing georeferenced<br>
photos.<br>
<br>
Solutions proposed:<br>
- Prune: very flakey on large numbers of traces, pretty tedious having<br>
to work in terms of ranges, pretty dumb how it sequences traces in the<br>
order you load them, not the order of their timestamps. The OSM<br>
background usually dies after a few minutes. Can't export ranges<br>
(instead you have to delete the rest of the trace).<br>
- EasyGPS: lacks the features I need. Fast though!<br>
- GPSu(tility): the "shareware" version is too crippled to evaluate,<br>
plus the interface looks pretty bad.<br>
- GPSbabel: only does conversion afaik, not editing.<br>
- GPSman: after 15+ minutes of going around in circles on the site, I<br>
can't even find the file to download. Or a clear statement whether it<br>
runs on windows. Plus it looks complicated to get all the right tcl/tk<br>
packages.<br>
- Viking: didn't work. Maybe my tcl/tk installation is broken.<br>
- JOSM: promising, but JOSM is always very slow on my machine, and I<br>
can't figure out how to edit gpx traces directly, other than<br>
converting them to data layers first. not sure if this will solve all<br>
my needs. I do like the colour highlighting though.<br>
- Garmin BaseCamp: may actually be able to do some of this, but<br>
unusably slow on large amounts of data, and has some really funky<br>
ideas about how to manage a "collection" of tracks.<br>
- Garmin MapSource: no editing of traces that I can see.<br>
- ExpertGPS: fast, seems to most of what I want (no useful overlays<br>
though), but $70 is a lot to spend on a tool that provides lots of<br>
features I can't use/don't want, like live GPS tracking<br>
<br>
So, maybe I'll use ExpertGPS till the evaluation period runs out,<br>
still looking for other good solutions though. Have I missed any?<br>
